Description
Technical field
The present invention relates to beauty, medical instrument field, more particularly, to a kind of sheet metal for promoting infiltration pen, have the metal
The idler wheel and rush of piece seep pen.
Background technique
For a long time, due to the barrier effect of skin appearance cuticula, make have the effects that treatment, health care or beautifying face and moistering lotion
Most drugs or skin care item because transdermal penetration rates are too low be difficult to reach expected from curative effect.In recent years, using base
The method that instrument carries out massage rush infiltration to skin, which is seeped, in the rush of micropin idler wheel has received common concern.This kind of idler wheel for promoting to seep instrument
On be uniform-distribution with the microneedle array being made of hundreds of micropins, apply needle mode by press and roll instrument in skin surface
The duct that a large amount of micron dimension sizes can be generated moment in keratoderma and epidermis then applies drug or beauty shield again
Skin product, it will greatly improve wherein active material and pass through cuticula and enter the penetrating power of epidermis, to be expected to obviously improve
The effect of drug effect or beautifying face and moistering lotion.
Summary of the invention
The present inventor has investigated the already present various rush based on micropin idler wheel in the market and has seeped instrument, and discovery is related
Rush in technology seep instrument have the shortcomings that following structure and, the microneedle array on existing micropin idler wheel is first as the core of instrument
There are mainly two types of structure types for part:
One is assembling after uniformly penetrating and being fixed in ribbon plastic supporting base by hundreds of discrete stainless pins
At.Since the spacing between the length and needle of single needle is smaller, processing is bigger with the difficulty of packaging technology, the uniformity of array,
Repeatability will be substantially reduced with yield rate, and cost is higher, the outer diameter (about 20 millimeters) of this micropin idler wheel and be protruded from
Spacing (about 2 millimeters) between the needle point on plastic supporting base surface is general all very big, and the length of needlepoint of protrusion is 0.25~1.5 milli
Rice.
Another kind is alternateed and is assembled by several circular ring metal pieces and annular gasket, wherein using sharp
The radial direction of the outer ring surrounding of the circular ring metal piece of optical cutting method preparation is uniform-distribution with the micropin of dozens of protrusion.It is this
Commercially available idler wheel/gasket the outer diameter for promoting to seep instrument is usually about 20 millimeters, between the needle point of the adjacent micropin of circular ring metal on piece
Away from can be contracted to 1.4 millimeters at present, but the distance between two neighboring circular ring metal piece be annular gasket thickness it is logical
Often about 2 millimeters.
It analyzes by inquiry, the existing micropin idler wheel assembled with the circular ring metal piece prepared based on laser cutting method is promoted
Seeping instrument, there are following main problems:
Firstly, the spacing between needle point is larger, about 1.4 millimeters.The limit of stimulated light machining accuracy and minimum process size
System, in the case where using sufficiently large laser power to guarantee cutting efficiency, the lines of laser cut line are usually wider and cut
It cuts precision to decline rapidly with the increase of sheet thicknesses, in order to which structure can be cut into rapidly on certain thickness sheet metal
Sharp keen and uniform needle point, the spacing between the length and needle point of micropin are just difficult to be made very small.Existing 100 microns thick
Only micropin length outstanding just has 2.5 millimeters to circular ring metal piece on outer circumference surface, result in so adjacent micropin needle point it
Between spacing it is larger, the density of microneedle array is less than normal.It therefore, can only be using increasing needle in such a way that skin surface rolls repeatedly
Hole density is thus difficult to realize effective control to the density of such perforation and its uniformity of skin to reach the mechanism declared
System, in addition will appear local skin because pinhold density is excessive disfeature the phenomenon that.
Secondly, the outer diameter of idler wheel is larger, usually about 20 millimeters.The skin of human body especially skin of face is very soft
Soft, exquisite and out-of-flatness, eyes and its peripheral part are especially delicate, once injured consequence is hardly imaginable.Because existing rush seeps device
The micropin idler wheel outer diameter of tool is larger, and the width of idler wheel is generally also almost the same with outer diameter, when use often only its
Middle very small part micropin can really touch skin, and the skin at some positions may be touched at all less than micropin, roll in this way
The utilization rate of wheel is not only very low, is difficult to obtain uniform mechanism, and is easy to injure the key positions such as eyes.In addition, big ruler
Very little micropin idler wheel instrument needs large-sized operation handle and larger sized instrument to protect structure, to make entirely to promote to seep device
Tool volume is larger, heavy, not readily portable.
Third, it is longer to protrude from idler wheel/gasket length of needlepoint, and about 0.25~1.5 millimeter.For the ease of manufacture and matter
Amount control, micropin length outstanding is typically set to 2.5 millimeters or so on the outer circumference surface of existing circular ring metal piece, it is therefore desirable to
Regulate and control protrusion idler wheel/gasket length of needlepoint using the annular gasket of bigger outer diameter and by changing its size.Human body skin
The barrier effect of the cuticula of about 10-40 microns of skin outer surface thickness is to cause most drugs or skin care item transdermal penetration rates
The main reason for too low, as long as micropin length can pierce through this cuticula and not depth and face nerve and capillary, energy
Both pain will not have been felt when reaching and significantly improve medicine-feeding rate or cosmetic result, and applying needle, will not have been caused bleeding, undoubtedly more
Securely and reliably., whereas if micropin is too long, not only pain sense is strong when applying needle, is easy bleeding and infects, and the micropin rolled can be chosen
It breaks facial tissue and causes biggish damage, therefore have the suspicion disfeatured.
In addition, using laser cutting stainless steel, the metals such as titanium the oxide skin of black and big can be generated on incision surface
The regulus or burr of protrusion are measured, these must be added using a series of subsequent corrosions such as pickling, electrochemical polish and cleaning process
With removal, both it is unfavorable for the environmental requirement of production, also influences machining accuracy；Due to being prepared using laser cutting method, circular ring shape gold
Outer circumference surface and the distance between the needle point outstanding thereon for belonging to piece are larger, and most of region between needle point will be deep in two
It is difficult to clean between a annular gasket, to bring security risk.
In short, inventor carries out extensive and deep investigation by seeping instrument to rush in the related technology, it is found
Practical effect often promotees the expection seeped there is also larger difference with massage, and also there are many more dispute, Ren Menzhi for safety
The present still generally waits and see to it.In addition, rush in the related technology, which seeps instrument primary limitation, cooperates anaesthetic in various beauty parlors
It uses, and is operated by professional, effect is usually different because of the technical level of operator, gets both praise and censure.
Compared with laser cutting method, the microfabrication that Wire EDM method carries out deep narrow slot to various metals has only
Special advantage, can reach micron-sized superhigh precision and very high surface quality, can obtain roughness Ra=0.1 micron
Mirror surface, and notch is not in the various burrs such as regulus of oxide layer and protrusion, therefore is also not required to carry out additionally special
Surface treatment.But cannot be directly used to punch or process the metal structure in hole using Wire EDM method, it must benefit
The through-hole for wearing silk is first got on workpiece with other methods, then by the molybdenum on electric spark linear cutting machine as cutting electrode
Upper silk, positioning could process the material of through-hole surrounding after being aligned again again after the through-hole on workpiece for silk or copper wire.
If processing the circular ring metal piece that above-mentioned outer ring surrounding has micropin using Wire EDM method, equipment is needed to constantly change
Punched, wear the series of processes such as silk, repeated disassembled and assembled molybdenum filament or copper wire, undoubtedly will it is very time-consuming, laborious, work efficiency is too low, difficult
To realize low cost batch production.
Therefore, under the premise of inventor has carried out investigation extensively and profoundly to existing micropin idler wheel, in conjunction with itself
The knowledge and experience accumulation grasped in terms of the fine processing techniques such as laser cutting, Wire EDM, in order to solve existing skill
One of technical problem present in art, the present invention propose that a kind of sheet metal for promoting to seep pen is somebody's turn to do in the case where guaranteeing that needle point is sharp keen
The size of sheet metal, the micropin length of outer circumference surface protrusion and micropin spacing can be made small, processing work efficiency and precision it is high,
Consistency is good, and can realize inexpensive batch production in an energy-saving and environment-friendly manner.
